My GS750 is starting to sound a bit tappety, so thought I`d check out the valve clearances. Unfortunately, my Haynes manual had a run in with an oil tray a couple of weeks ago, and the page I want for the settings is no longer readable !. I seem to recall that the clearance for both inlet and exhaust was 0.030mm-0.080mm, but am not certain. The bike is a 1979 GS750, unsure which model though. Anyway, if anyone can tell me the settings that would be great. Also, any tips for depressing the valves to get the shims out. I have the tool for holding the buckets down, and in the past have used a screwdriver under the cams to lever them, but its a bit tricky on the valves for pots 2 & 3, and I worry about catching the cam lobes and damaging them. Just wondered if there is a special tool for this.
